Paper Abstract

Using fluorescence activated cell sorting we have compared the binding of a number of porphyrins with different polarity by blood cells. According to pigment level blood cells may be arranged in order granulocytes greater than or equal to monocytes greater than lymphocytes greater than erythrocytes. Cellular accumulation of selected porphyrins in blood cells was remarkably different. The equilibrium level of chlorin e6 dimethylester in blood cells was about 15 times higher compared with chlorin e6. As a result, the percentage of pigment binding by blood cells varied from 0% (of total amount) in the case of polar pigments to about 50% for moderately apolar porphyrins. The results obtained show that pigment binding to blood cells may be of certain value when the pharmacokinetic behavior of porphyrin sensitizer is analyzed.
